describe oasis

Any stranger entering the oasis must be given food and shelter during their stay in the oasis; it is the law of hospitality. The oasis is considered a safe-haven. Weapons are also forbidden in the oasis. It's in the oasis that Santiago searches for the Alchemist and is introduced to the elders who put forth quite a challenge for Santiago to fulfill.

The oasis is a beautiful area of the desert. There are many colorful tents and colors fill the scene. It serves as not only a literal contrast to the desert itself, but also as a metaphorical contrast to the "outside" world, the world of Santiago's quest to fulfill his personal legend. It's a respite from the rigors of the journey for Santiago and any other traveler who happens upon it.
